The DSP extensions add multiply-accumulate functions to the ARCtangent to deliver more computational power, ARC claims. In addition to these extension instructions, the available XY memory increases data throughput. These features permit the ARCtangent to address more complex DSP applications than typical RISC/DSP cores, while maintaining RISC functionality, the company said.
